Abstract

Combining tympanoplasty with mastoidectomy in child subjects is considered beneficial assuming the vital role of the mastoid in middle ear ventilation owing to the immature system of the Eustachian tube. Aim: The present study aimed to assess the surgical advantages of type 1 tympanoplasty with and without mastoidectomy in child subjects having chronic suppurative Otitis media with tympanic membrane perforation. Methods: The present retrospective study assessed pediatric subjects (<18 years) that underwent type 1 tympanoplasty for chronic suppurative otitis media. The subjects were divided into 2 groups namely tympanoplasty with canal wall-up mastoidectomy and tympanoplasty without mastoidectomy. Surgical success was considered for intact tympanic membrane and no recurrence of disease after 2 years of follow-up. Results: In Group I, type 1 tympanoplasty alone was done in 30.5% (n=36) of study subjects, and tympanoplasty and mastoidectomy in 69.5% (n=82) subjects of Group II. In Group I, preoperative ABG was 20±10.3 and in Group II, it was 16±10.5. Postoperatively, ABG was higher in Group I at 9.4±7.3 compared to Group II where it was 5±6.3. However, the difference was statistically non-significant with p=0.09. The mean gap closure was lower in group I with 12.3±9.3 dB and was higher in Group II. The difference was statistically non-significant with p=0.34. The success rate for Group I (tympanoplasty with mastoidectomy) was 90.2% (n=74) subjects and 88.9% (n=32) for Group II (tympanoplasty alone). The difference was statistically non-significant with p=0.73
